GAS BURNER.

Applioatonled February 27, 1922. Serial No. 539,364.

To all whom t may concern:

Be it known that I, TWILLIAM V. ROBIN- soN, a citizen of the United States of America, residing at Cwosso, in the county of Shiawassee and State of Michigan, have invented certain new and useful Improvements in Gas Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to gas burners more particularly designed for use on open top gas ranges and the invention consists in the novel construction as hereinafter set forth.

In the drawings: Y

Figure l is a longitudinal section through the burner;

Figure 2 is a top planY view thereof.

Figure 3 is a cross-section on line 3 3 of Figure 2. v i

In the use of gas stoves and ranges there is a 'great iiuctuation in the pres we at which the gas is delivered at different es Consequently, an adjustment of the burner which is satisfactory for one pressure is not as good for a higher or lower pressure. In particular, where, as is usually the case, the gas jets are directed upward, there must be suiiicient space between the burner and the vessel to be heated so as not to inter iere with combustion. If the gas pressure is strong, a greater distance is required than where the gas pressurevis weak. On the other hand, if the height of the vessel above the burner is proper for strongl pressure Vwith a weak pressure, the heating effeet will be greatly reduced. l

It is the primary object of the present invention to obtain a .construction where a variation in gas pressure will not require any change in the distance between the burner and the vessel to be heated and also one where in the lowest pressure an ethcient heating effect is produced. This I have accomplished by forming the burner with an imperforate top and with the gasV extending jet apertures E slightly beneath.

said top. At the center the inner ends'of the arms C merge into each other and at the center there is an aperture F for a supply of air from beneath the burner. With the construction as just described, when the burner is in operation, the jets will all be directed laterally and, therefore, increase or decrease in gas pressure will only change the length of these jets without materially changing the distance between the jets and the top plane of the burner. The burner is therefore placed in the. range 'so as to be but a. short distance below the bottom oiiV the vessel' to be heated and the flame, whether the jet is large or small, will be in close proximity to the vessel.y The arms C being of a wedge-shaped form, or greater in width at the bottom than atthe top, has the effect of shielding` the flames from too strong an air draft. Theretore,'in operation, satisfactory resultsmay. be obtained under very different pressure conditions of the gas. Y

W hat I claim as my invention is:

A. one piece burner comprising a series of radially extending' arms connected together at their inner ends, each of said arms having a rounded bottom and allat top, the

sides of each arm tapering graduallyupward from the rounded bottom to the flat top and having a plurality orn openings therein for directing the flames laterally. In testimony whereof I atx my signa` ture.

WILLIAM V. ROBINSON.
